Not able to get refresh_token in response

Hello everyone,

I am using the API [https://bitbucket.org/site/oauth2/authorize?client_id=

&response_type=token|https://bitbucket.org/site/oauth2/authorize%3Fclient_id%3D%7Bclient_id%7D%26response_type%3Dtoken] to get access_token but access_token is expired in 1 hour and I need refresh_token but I am not able to get refresh_token in the above API response. Or is there any other way to get refresh_token.

As well I wanted to call this API as GET API.

Can please someone help.

Thank You!
